【摘要】 以马来酸酐和淀粉为原料合成了马来酸酯化淀粉，在逆相乳液聚合体系中合成了马来酸酯化淀粉－丙烯酸共聚物微球，微球粒径主要在２０～４０μｍ，探讨了酯化度、表面活性剂、水相浓度以及转速等对微球制备的影响。更多还原

【Abstract】 tarch microsphere can easily be prepared by copolymerization of maleic starch ester with acrylic acid in a wa-ter-in-oil emulsion. The microsphere,preferably around 20～40μm in diameter,will have a microporous structureformed by the network. Effects of preparative condition on the microsphere are investigated.更多还原
